Problems solved by technology

[0004] Although the aforementioned invention patent can achieve the purpose of reducing waste because the end edges 12 of the chain pieces 10 in the same row are connected head to tail, after cutting, there is still a section between the chain piece units 1 arranged at intervals along a width direction 32 Strip-shaped waste 33, so although the aforementioned invention patent can reduce cutting waste, the waste that can be saved is limited, and the cost of materials is relatively high

Abstract

The invention provides a chain sheet punching method. A plurality of rows of chain sheet units can be punched on a metal plate and strip, each row of the chain sheet units comprise a plurality of chain sheets connected end to end, the metal plate and strip intermittently proceeds in a length direction, and each chain sheet is provided with two straight edges parallel to the length direction, two end edges respectively connected with the straight edges and arranged in tandem at intervals, and two penetration holes respectively close to the end edges. The chain sheet punching method comprises the following steps: a punching step for forming penetration holes of a chain sheet and a blanking step for forming the outline of the chain sheet, wherein in the blanking step, the end edges of the chain sheets in each row of chain sheet units to be cut are connected end to end, and the straight edges of the chain sheets in the chain sheet units which are adjacent left and right are staggered in tandem and partially overlapped. Through the design, the purposes of reducing waste materials and lowering the material cost are achieved.

Description

technical field [0001] The present invention relates to a punching method for chain pieces, in particular to a punching method for chain pieces used to manufacture chains. Background technique [0002] refer to figure 1 , is an invention patent of CN103286255A, which discloses a manufacturing method of a chain piece that can reduce waste. The manufacturing method uses a punching method to punch out several rows of left and right spaced chain piece units 1 on a metal strip 3, each The chain sheet units 1 all have several chain sheets 10 connected end to end along a length direction 31, and the chain sheets 10 all have two left and right parallel spaced straight sides 11, two arcs and are connected on the straight sides. The end edges 12 on the front and rear sides of the edge 11 and the two through holes 13 spaced in front and rear, each end edge 12 has a straight section 121 . [0003] And this manufacturing method at first prepares this metal strip 3, and makes this metal...
